If some elements were added before and some after the default path,
wouldn't it be possible to determine that when parsing the path, and
then use addpath to append/prepend as necessary?

There is no need for the [] if there is only one return value, so
please write

  function subpaths = parsepath (p)

instead.

| +  pat = '([^:]+[:$])';
| +  [S, E, TE, subpaths] = regexpi(strcat (p, ':'), '([^:]+[$:])');
| +endfunction

To avoid confusion with the transpose operator, please use " to
delimit strings.  Also, for consistency with the rest of Octave,
please avoid upper-case variable names.

Instead of making this public, which will allow users to modify it,
please create a static function that returns the value instead.  Then
the value will still be protected from having users change it.
